httpd and mod_wsgi ran with wrong python version
I am deploying django project with httpd on RHEL7. And changed the system default python version to python3.4. But after I restarted the httpd, it still used python2.7. I searched a lot and it mostly because of mod_wsgi was built under wrong python version. However, I checked that mod_wsgi was installed under python 3.4. May I know how to make it run under the correct python version? Not too sure if httpd has default python version... Thanks very much for your help! enter image description here -
Forbidden (CSRF token missing or incorrect.) - even though it's included
I keep getting the above error even though I have included a csrf_token already. I've used the same csrfmiddlewaretoken for my other ajax calls and it works fine but here im getting the forbidden error. Any idea why?

get access to serializer validated data DRF
all the django rest framework docs assume your going to instantly save the data. But what if I want access to the serializer data? What if I want to do something with it. Or if the serializer contains info other than what I need to save in a model? is the validated_data attribute what we need? So validatedData = serializer.validated_data userid = validatedData.get('id') would work right? -
DJango CreateView not setting DB Key with Class-Based Views
I am using CreateView from DJango to save data to the DB. To do this, I am following the instructions here: Form handling with class-based views According to my understanding, after the data is saved to the DB, the control is to be passed to a type of "success screen" - in this case, for my scenario, control is to be passed to a "details page". The details page is represented by the following URL: url(r'^owner/(?P<pk>[0-9]+)/contact/details/$', views.MstrstoreheadcontactDetailsView.as_view(), name='owner-contact-details'), Below (in the class Mstrstoreheadcontact) the "details page" is being called by the get_absolute_url function (which is part of the Mstrstoreheadcontact model) from the models.py file class Mstrstoreheadcontact(models.Model): tenantid = models.ForeignKey('Mstrauthowner', models.DO_NOTHING, db_column='tenantid', blank=True, null=True) contactid = models.BigIntegerField(primary_key=True, default=0) genderid = models.BigIntegerField(blank=True, null=True, default=0) firstname = models.CharField(max_length=20, blank=True, null=True) lastname = models.CharField(max_length=20, blank=True, null=True) officephoneno = models.CharField(max_length=20, blank=True, null=True) cellphoneno = models.CharField(max_length=20, blank=True, null=True) class Meta: managed = False db_table = 'MstrStoreHeadContact' def get_absolute_url(self): return reverse('masterdata:owner-contact-details', kwargs={'pk': self.contactid}) For me the code: return reverse('masterdata:owner-contact-details', kwargs={'pk': self.contactid} is supposed to take the control to the "details page" that will display the new record that has been added to the DB. The problem When the code above is executed, the variable self.contactid is set … -

Django rendering a db field in the template
Could anyone correct my code? Background: The user, once on the 'start.html' template, will enter their name and press submit. Then on the next template, 'game.html', there should be a paragraph tab that contains that users name. Problem: I must be writting something incorrectly because the user's name does not render on the 'game.html' template. Or, I could also be storing it wrong.

Saving Blog in Django with figure, Space, paragraph, link
I am from embedded field but trying to learn web development and using Django for this purpose and using Postgresql as a back-end database. Questions can be silly but please understand that my level is beginner. I am making one website in which user can write new blog entries. For this purpose, I am using Textarea to let user write the blog entry. My questions are 1) Is there any good text editor which i can embed in my website and let user write their entries. Right now, i can only write text but can't choose the font, upload pic, or format the text. 2) I am thinking to store the link to figure in the database and uploading the pic to the google drive or dropbox. is this good practice? can you recommend some other method? 3) How can i let the text saved in the database to know when to start a new paragraph? HTML tag will be enough, or do i need to use some other method? -

How to save an array of object in DRF
I have this type of json: { "word" : "world", "days" : [1, 3, 7] } And DRF gives me this error: 'days': [{'non_field_errors': ['Invalid data. Expected a dictionary, but got int.']}, This is my days serializer: class DaysSerializer(serializers.ModelSerializer): class Meta: model = Days fields = ('day') And this my top level serializer: class WordsSerializer(serializers.ModelSerializer): days = DaysSerializer(many=True) class Meta: model = Words fields = ('word', 'days') I read that I need to use bulk serializers. Is that the route that is recommended today? Or there is a simpler way? If I need to use the bulk serializer library, I don't understand from their example how do I use that library for my purposes? Namely to (bulk) save the many to many entries (the Days) in one of the records (the Word). -

Run multiple local terminal processes with Fabric
new to using fabric. I have a project with a django backend and angular front end. I'm trying to make running the project locally easier with a fabfile. Here is the part of the script where I'm stuck... # activate venv and start backend server with lcd(projectpath), prefix('. venv/bin/activate'): local(projectpath+backendfolder+'manage.py runserver') # start frontend server <==== FAB STOPS HERE!! with lcd(projectpath+frontendfolder): local('npm start') I have managed to get my virtual environment started and manage.py runserver to work. However fabric stops there and doesnt continue executing starting my angular server. This is obviously because this is a serial process. How can I get the angular server running as a new terminal process after my django server is running? -

Articles written by 'Tom' and 'Sara' would match. But, Articles written by 'Tom' and 'Alter' would NOT match. -

Django create CustomUser model

However, I keep on getting the following error when migrating: ValueError: The field admin.LogEntry.user was declared with a lazy reference to '<app_name>.user', but app '<app_name>' doesn't provide model 'user'. What I have done so far is the following: In app/models.py added CustomUser class together with CustomUserManager with relevant fields and all.

Django doesn't check passwords when reset
I'm using Django's password_reset forms with overriden html files, and when I pushed my code to my server, I could suddenly make the password 1 character long, where they should at least be 8 characters long. BUT it does show an alert if password1 and password2 aren't identical On my local machine the Django project was created using 1.11.3, and on the server the Django project was created in version 1.8.7.The form I use for posting the new password: <form method="POST"> {% csrf_token %} <input name="new_password1" class="form-control" type="password" placeholder="Adgangskode"> {% for key, value in form.errors.items %} <strong>{{ value|escape }}</strong> {% endfor %} <input name="new_password2" class="form-control" type="password" placeholder="Bekræft adgangskode"> <input type="submit" class="btn btn-default btn-block" value="Bekræft"> </form> The question is: why does Django not properly validate the password (checking if it's are entirely numeric, or if it's longer than 8 characters), on the server, but perfectly on my local machine? Thanks -
Django: Redirect is Not Working

So, how can I redirect user to the same page after Like?
